Abstract
The present invention generally relates to providing a controlled impedance connection between two PCBs. A connector may connect a first PCB to a second PCB. The connector may comprise of a body made from a dielectric material and a plurality of conductive lines defined in the dielectric material. One or more of the conductive lines may transfer one or more signals between the PCBs. A return path may be provided for each signal line. Furthermore, the width, length, and the proximity of a signal line and its associated return line may be selected to match the impedance of the connector to the impedance of the PCB. The connector may also contain one or more ferrite layers to suppress electromagnetic radiation caused by common mode currents.
